Hydraulic Dock Lift Optional Accessories

By including options to the basic dock lift offering, safety and security at any loading dock is possible! Choose Pentalift dock lifts when specifying a new or existing construction project and refer to our sales team when considering the below options.

Platform width

Platform Length

Dock lift vertical travel

The difference between the fully raised height of the lift deck and the fully lowered height of the lift
.

Capacity

The maximum load (evenly distributed) that the dock lift can accomodate and lift.

Capacity End / Side Axle load

The maximum amount of single axle load (in the case of
rolling loads) which can be applied to the loading edge of the platform (end or side) when
the lift is in any raised position. This rating considers: 1) that some amount of deflection
will occur during load transfer, 2) the moving and impact forces imposed by the load, 3) that
this is a temporary condition during load transfer only, and 4) that the scissors lift platform is
static and non-
moving

Capacity End / Side Edge Load

The maximum amount of static load that can be applied to the
edge of the platform (end or side) when the lift is in any raised position. This rating
considers: 1) that some amount of deflection will occur during load transfer, 2) that this is a
temporary condition during load transfer only, and 3) that the scissors lift platform is static and non moving.

Lowered height

The height of the top of the lift patform, in the fully lowered position.

Hinged Bridge - wider

A wider version of the hinged bridge -built to specific application requirements.

Hinged Bridge - Longer

A longer version of the hinged bridge - built to specific application requirements.

Hydraulic power unit voltage

The power supply voltages available include 115 and 220 volt single phase. 230, 460 and 600 volt 3 phase. 380 3 phase 50 hertz voltage is also available. 3 phase voltages are recommended where possible to avoid any line loss issues.

Hydraulic power unit horsepower

For any given lift, increasing the horsepower rating of the power unit increases the lifting travel speed of the lift.

Electrical Options - Up Travel Limit Switch

This option utilizes a limit switch that stops the units upward travel at a preset travel dimension every time.

Electrical Options - Overhead Door kit

A limit switch and a mechanism for activating the limit switch by the overhead door is provided. This interlock prevents the dock lift from being activated unless the door is in a sufficiently raised position.

Automatic Hydraulic Roll-Off-Stop

A hinged bridge that is hydraulically connected to automatically raise as the lift moves from the fully lowered position upward. The bridge raises to prevent the wheeled vehicle from accidentally rolling off the lift platform as it raises.

Guard Rail Options – Additional guard rails

Additional perimeter guard rails are provided to suit the application.

Spring Assist

This one piece hinged bridge spring assist requires one guard rail or chain post for attachment. Also available for split hined bridge.

Dock Lift Bridge Assist - Hydraulic

Hinged Bridge – 2 piece

This two piece hinged bridge requires two guard rails or chain posts for attachment. It facilitates easier lifting of the bridge by splitting the weight.

Hinged Bridge - aluminum

This provides a lighter lifting requirement for the bridge.

Toe Sensor

A bar that is electrically interlocked, surrounds the lower perimeter of the lift's platform and electo/hydraulically arrests the downward decent of the lift when an obstruction is encountered.

Pit Curb Angle

Steel angle iron with tab anchors welded along it are provided and embed into the edges of the dock lift pit. The curb angle provides a metal edge protects the pit edges from breaking away during fork lift roller overr.

Retaining Cradle and Wear Plates – LPE Only

This option increases the end edge load rating of the dock lift while keeping it in place during loading and unloading. It provides steel tracks for the lifts leg rollers to run on. It eliminates wear and tear on the installation surface.

Controls – Removable push button on post on platform

A post with the control push button on top of it on removable cord is provided on the platform of the dock lift. This option is utilized on dock lifts on which a fork lift will be driving on and being raised or lowered.

Controls – Push button on post on platform

A post with the control push button on top of it is provided on the platform of the dock lift. This option is utilized on dock lifts on which a fork lift will be driving on and being raised or lowered.

Smooth Platform

Checker / safety tread plate is replaced with a smooth platform deck surface with abrasive non-slip strips. Commonly used to reduce vibration during the movement of traffic across the platform.

Portable Dolly Handle –LPE Only

This is an attachment which can be placed on the portable version of the dock lift in order to move the unit. Note: The effort required to move the unit is high. The turning radius is typically large..

Manual Lowering Valve

A manually activated valve is provided to facilitate the lowering of the lift in the event the power supply to the lift is lost.

Controls – 2 second bell / buzzer signals dock lift in use

A warning buzzer or bell sounds for 2 seconds whenever the dock lift is activated to raise or lower.

Controls – Wall installed push button

The control push button is mounted on the building’s interior wall within close proximity of the dock lift.

Controls – key operated control station

Control is keyed to only allow use to anyone with the key.

Dock Lift Night Locks

This option provides a means to mechanically hold the dock lift deck at the same level as the top of the pit. This option is typically utilized in applications with a full depth pit. The four mechanical arms are manually rotated into the engaged position when required. The arms are rotated out of the engaged position when not required. In applications for which it is important for the lift platform to maintain level with the top of the pit, the night locks address concerns created by hydraulic valve leakage allowing the platform to very slowly lower over extended periods of time.

Hinged Approach Ramp

More typically supplied on surface mounted dock lifts. It is a hinged ramp bridging access from the floor to lift platform.

Hydraulic Dock Lift Bridge Assist

This hydraulic bridge assist is installed on the top platform surface of the lip. It improves safety, ergonomics and efficiency in positioning bridges or lips of this heavy nature. More info.

A lightweight and compact deck mounted power unit is installed inside of a custom steel enclosure that can be installed on either side of the platform. It is available in 1HP, 3HP, and 5HP versions depending on lift speed requirements.
